AIM: To investigate the impact of uveitis macular edema on vision and vision field impairment.METHODS: This study was a single center, retrospective controlled study of clinical characteristic found in the middle, rear or panuveitis treatment. Totally 132 patients(248 eyes)with uveitis macular edema were selected and accepted the vision, the frequency-domain optical coherence tomography, micro-perimetry examination.RESULTS: Uveitis macular edema had significant correlation with visual acuity

... visual field damage(P<0.05). Different types of macular edema corresponded to different visual impairment: not associated with foveal thickness increased cavity type could produce moderate visual impairment, with an average 10 letters; not associated with cysts and only foveal thickness increases type could produce a greater degree of visual impairment, with an average 19 letters; and accompanied by cysts, foveal thickness increased cystoid macular edema type could produce the greatest degree of visual impairment, with an average 26 letters. All selected macular edema had varying degrees of vision impairment: closely related to the thickness of the fovea, that the greater the thickness, the wider the range of vision impairment, the difference was statistically significant(P<0.05), regardless of whether cysts had little relationship. CONCLUSION: The damage of macular edema corresponding visual function prompts us later in the course of uveitis treatment, the treatment of macular edema should also serve as an important aspect to focus on. Assessment of macular edema, uveitis visual impairment should be to focus on the vision and the vision of both micro and so on.
